Quarrying Process And Quarry Products

Stone quarrying is the multistage process by which rock is extracted from the ground and crushed to produce aggregate, which is then screened into the sizes required for immediate use, or for further processing, such as coating with bitumen to make bituminous macadam (bitmac) or asphalt. The process begins with a detailed three-dimensional survey of the quarry face. This allows the explosives,Rock Crushing Process in Mining,15/05/2017· Rock Crushing Process in Mining. Post navigation. Previous. Next . Let’s follow a rock through a crushing cycle to see what variables will have to be controlled. First the rock will enter the crushing chamber and drop as far as the angle of the crushing surface will allow it to.
